Description

Description: TECHNICAL FIELD The present invention relates to a method for guiding a parent-child guided flying vehicle including a large number of sub-munitions having a guidance control device.

[Conventional technology]

FIG. 4 is a cross-sectional view of a conventional parent-child type guided air vehicle, and FIG. 5 is a diagram showing a state in which the conventional parent-child type guided air vehicle searches for and tracks a target. (15) is a close bullet seeker, (2) is a close bullet steering control device, (3) is a close bullet steering wing,
(4) is a master bullet propelling device, (5) is an inertial device mounted in the master bullet, (6) is a sub-shot, (7) is a sub-seeker, and (10) is a target group.

Next, the operation / action will be described. In FIG. 5, the main bullet (1) confirms its own flight path based on the information of the inertial device (5), and drives the steering wing (3) by the steering control device (2) to correct the position error and fire it. It flies over the area where the previously input target group (10) is present, and ejects a submunition (6). Each of the released submunitions (6) searches and tracks the target group (10) by the submunition seeker (7) and attacks.

[Problems to be Solved by the Invention]

Since the conventional parent-child guided vehicle guidance method is configured as described above, there is a target group in the parent-child ammunition that has been recently extended in range due to the guidance error due to inertial guidance in the first and middle period. There is a danger that a submunition will be ejected to a point outside the target area and the submunition Seeker will not be able to find the target no matter how much the investigator searches, or miss lock-on to something other than the target. A method of increasing the geometric lock-on probability of sub-bullets is to search and capture the target before the sub-bullet is ejected and to eject the sub-bullet toward the target. I had to equip the ammunition with a seeker, which had the problem of significantly increasing both cost and size.

The present invention has been made to solve the above problems, and accurately captures a target position before ejecting sub-munitions without equipping the main bullet with a seeker again, and reliably ejects the sub-bullet toward the target. The purpose is to obtain a guiding method in which the geometric lock-on probability of the sub-bullet is significantly improved.

[Means for Solving the Problems]

In the parent-child guided vehicle guidance method according to the present invention, a large number of sub-bullets that are contained in a parent bullet are arranged in an array, and the antenna position, transmission radio wave output, transmission frequency, etc. of each sub-bullet are controlled. By combining the received waves received by each of the sub-munitions and having a control device for signal processing in the main bullet, it is as if one sub-lens seeker was seen as one element It has a function like a fused array radar, and it can be used as a substitute for the main bullet Seeker.

[Action]

According to the parent-child guided flying vehicle guidance method of the present invention, a controller mounted in the parent bullet makes a large number of sub-bullets into a fused array radar and outputs radio waves transmitted from each sub-lens seeker. By synthesizing them, the master bullet catches the target group from a long distance before the slave bullet is discharged, and the slave bullet is surely discharged toward the target group, thereby improving the geometric lock-on probability of the slave bullet.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. First
1 (a) and 1 (b) are parent-child type flying vehicles according to the present invention, wherein FIG. 1 (a) is a sectional view and FIG. 1 (b) is a sectional view as shown in FIG. 1 (a). FIG. 3 is a cross-sectional view of the flying body in the direction of arrow A shown in FIG. 1 (a), in which (1) is a master bullet, (2) is a master steering control device, (3) is a master steering blade,
(4) is a propulsion propulsion device, (5) is an inertial device mounted in the propulsion bullet (1), (6) is a sub-shot, (7) is a sub-seeker,
(8) is a sub-munition grasping device which is provided in the main bullet (1) and has a role of a launcher of the sub-bullet (6) and an electric signal connector of the sub-lens seeker (7). A slave bullet control device that can send and receive signals to and from the slave bullet seeker (7) through the grasping device (8), (10) is a target group, (11) is a target search start point, and (12) is The emission point of the sub-bullet (6), (13) indicates the radio wave transmitted from the sub-lens seeker (7), and (14) indicates the reflected wave from the target (10).

Next, the operation / action will be described. In FIG. 2, the fired main bullet (1) confirms its flight path by the inertial device (5) during flight by the main bullet propulsion device (4),
The main steering wheel (3) is driven by the main steering control device (2) to correct the trajectory, and inertia is guided to the search start point (11) near the target group (10) input in advance before launching. .

In FIG. 1, the sub-bullets (6) housed in the front of the main bullet (1) are arranged in an array, and each sub-bullet (6) has a sub-bulb seeker ( 7) are separately controlled by the sub-lens seeker controller (9).

At the search start point (11), the parent bullet (1) is a slave bullet seeker (7) in response to a command from the slave bullet seeker control device (9).
Operate simultaneously, and the output is combined by matching the beam directions of the respective sub-lens seekers (7), and the parent bullet (1) acts on the entire sub-lens seeker as if it had a fused array radar, Search the target group (10). Goal group (10)
The master bullet (1) that has captured is driven by the master steering wheel (3) by the master steering control device (2) until it reaches the slave discharge point (12) within the range of the slave (6). When the target tracking is performed and the sub-bullet ejection point (12) is reached, the sub-bullets (6) on the outside are sequentially ejected. In FIG. 3, the emitted submunition (6) irradiates the target group (10) with a radio wave (13) and receives a reflected wave (14) to start tracking the target.
On the other hand, the sub-lens seeker control device (9) controls the sub-lens seeker (7) of the sub-lens (6) remaining in the parent bullet (1) at any time, and continues to transmit a stable beam without a single piece. , Since the main bullet (1) can always keep track of the target group (10), it can cope with a wide target area.

In the above description, it was described that the outputs of the entire sub-lens seeker were combined to form one beam to search for the target. However, similar to the ordinary fused array radar, the sub-lens seeker controller (9) The control divides the beam into multiple beams (reduces the number of sub-lens seekers that form one beam) and simultaneously searches multiple regions, or tracks one target group while searching another target group (TWS = It is also possible to perform track, whirl, and scan, which is also effective for target areas with scattered target groups. In the above description, the sub-lens seeker (7) is described as if it is active homing using radio waves as a medium, but there is no problem whether the sub-lens seeker (7) is radio passive or infrared passive. Instead, it is possible to capture the target group as an image.

In addition, one or some of a large number of sub-lens seekers may be infrared passive seekers, and the rest may be radio-active homing seekers, or the frequency of radio waves may be changed by a part of the sub-lens seekers to form a composite seeker. Is. Moreover,
By selecting the sub-munitions that are the same as the main bullet itself and equipped before launching the main bullet, a suitable type according to operating conditions (target specifications, type of area where the target exists, ambient environment such as weather and time) The composite seeker can be set easily (however, the sub-seeker control device (9) needs to have a mode selection function according to the type and operation of the composite, and it is necessary to pre-set when loading sub-units).

〔The invention's effect〕

As described above, according to the present invention, a large number of sub-bullets are arranged in an array, the sub-lens seeker is controlled in the main bullet, and a control device capable of processing each received signal in a unified manner is provided. Since it can play the role of a master bullet seeker in the whole number of slave bullet seekers, there is an effect of increasing the geometric lock-on probability of the slave bullet without particularly equipping the bullet bullet seeker.
